Automated teller machine and control method thereof

An automated teller machine comprising:

• a bundle receiving unit in which a bundle of mediums are input;
• a discrimination unit that receives the mediums from the bundle receiving unit and discriminates the mediums;
• a temporary holding unit that temporarily holds the mediums discriminated in the discrimination unit;
• a conveyance path for conveying the mediums between the discrimination unit and the temporary holding unit;
• and
• a controller that controls the bundle receiving unit, the discrimination unit, and the temporary holding unit,
• wherein when the mediums on the conveyance path are returned to the bundle receiving unit, the controller controls the bundle receiving unit such that the mediums on the conveyance path are stacked in a single bundle with the mediums stacked in the bundle receiving unit,
• wherein the bundle receiving unit includes:
• a bundle transport unit including a first bundle transport unit and a second bundle transport unit that are spaced apart from each other to face each other to provide a stacking space in which the bundle of mediums are conveyed;
• a semi-separation unit that allows a preset number of mediums to pass therethrough from the bundle receiving unit;
• and
• a sheet separation unit that separates the mediums that have passed through the semi-separation unit into individual sheets,
• wherein the semi-separation unit includes:
• a semi-separating roller providing a gap, between the semi-separating roller and a lower surface of the sheet separation unit, for allowing a preset number of mediums to pass therethrough;
• and
• a bill press, on which the semi-separating roller is disposed, selectively movable up and down and rotatable in an inclined state, and
• wherein when the mediums on the conveyance path are returned to the stacking space, the controller controls the bill press to be inclined upward toward the stacking space.

A control method of an automated teller machine, comprising:

• a medium input step of inputting a bundle of mediums in a stacking space of a bundle receiving unit;
• a medium conveyance step of conveying the mediums input in the bundle receiving unit through a conveyance path;
• and
• a media return step of returning the mediums being conveyed through the conveyance path to the bundle receiving unit when a failure occurs during the conveyance of the mediums,
• wherein in the media return step, the mediums are returned to the bundle receiving unit so that the mediums on the conveyance path are stacked in a bundle with the mediums stacked in the stacking space,
• wherein in the medium return step, an uppermost medium located at the top among the mediums stacked in the stacking space is moved in a direction opposite to a deposit direction to be laid on a bill press of the bundle receiving unit.
